In August 2013 The College Ystrad Technology course to survey the Mynach and Coleg Morgannwg electrical workshop on campus. merged to become Coleg y To ensure that each student in the Cymoedd which means College class was involved in this project, of the Valleys. By joining together Stephen Ward (course tutor) created Task Coleg y Cymoedd is now one of four separate project teams to Survey the electrical workshop on the largest futher education ascertain the 3D model of the campus to ascertain the 3D model providers in with an building. The challenge for each of the building estimated 20,000 learners project team was how to survey choosing to study and over this complex structure with different Solution 1000 members of staff. Coleg room sizes, floor and wall variations Leica 3D Disto was used to survey y Cymoedd has several campus and produce a 3D model of the the internal partitions and external locations throughout the structure within the given time frame. area of this complex structure Boroughs of Rhondda Cynon Results Taff and Caerphilly offering its Solution The measured data was transferred own unique learning environment. The surveying process was categorised into a CAD modelling software to into three different stages. The first achieve the 3D model of the building “We were able to survey the building was to survey the external building. areas where it would have been The next stage was to measure up impossible to do with a conventional the different partitions internally tape / measuring device.” including the different wall variations, Stephen Ward, Corse Tutor, windows, doors and stairs. The final Faculty of Technology & Built stage was to integrate the two Environment for Coleg y Cymoedd surveyed data sets together to obtain a 3D model of the building. Challenge A group of HNC students in the Faculty To help them to achieve this goal of Technology & Built Environment within the limited time frame, the were tasked as part of their Building students opted to use the Leica Product highlights • Measure plan position, height and distance in all three spatial axes • Precision: accurate to 1mm at 10m • Integrated camera • Digital pointfinder with 8x zoom for precise pointing over longer distances • Wireless connection between sensor and hand-held unit eliminates the hassle and limitation of cables • Hand-held unit with a modern touch screen, high resolution colour display • Recording information in the form of standard tables, photos, DXF files, text files at the press of a button
